As all Yachtsman will know, regularly varnishing your vessel’s woodwork is essential to ensure it stays in mint condition. Routine use in the sun exposes your boat’s woodwork to harmful UV rays as well as salt water, both of which work in unison to break down the varnish protecting your boat’s woodwork.
Deteriorated varnish opens up your woodwork to a number of risks including rotting, cracking and even leaking. All of which can practically ruin your boat's resale value.
